The NDNS is a continuous programme of fieldwork designed to assess the diet, nutrient intake and nutritional status of the general population aged 1.5 years and over.
This is not the latest release in the series: National Diet and Nutrition Survey Rolling Programme (NDNS)
This report provides background information on the NDNS, including sampling and methodology, and presents findings from the Wales Years 2 to 5 combined report on food consumption, nutrient intake and nutritional status.
The combined results from Years 2 to 5 is the first time that representative data for Wales from the NDNS RP have been available. The data will inform nutritional surveillance in Wales; assist in evaluating existing policies; and set future, evidence-based policy direction.
The main report presents combined results from Years 2 to 5 combined of the NDNS RP for the Wales sample, designed to be nationally representative. It follows the same general format as the UK Years 1 to 4 combined report including types and quantities of foods consumed. It also compares intakes of key foods and nutrients in Wales (Years 2 to 5 combined) with the UK as a whole (Years 1 to 4 combined) and by equivalised household income and deprivation indices. The report also includes findings from blood indices of nutritional status and information on Body Mass Index (BMI), blood pressure, blood cholesterol levels and the socio-demographic characteristics of the participants.
Salt intake data are now included. The analysis was not ready for the original publication.
Consumption estimates for fruit and vegetables, fruit juice and “5-A-Day” portions, including composite dishes, have been corrected for an error in which food groups which should have been excluded from the 5-A-Day calculation were mistakenly included. The corrected values for Years 2-5 are therefore slightly lower than the values originally published but the overall conclusions on fruit and vegetable consumption are unchanged. Details of the methodology for estimating fruit and vegetable consumption and calculating “5-A-Day” portions can be found in Appendix A.
